if you've selected YES to DATA INIT then its back to factory defaults.

The car is now ready for the self idle learn procedure. You simply need to do this. If the idle is jerky and unstable. Turn car to ACC, do DATA INIT again. Turn car off. Turn car on and follow idle self learn procedure, its in the FAQ in my signature

if you dont perform the self idle learn procedure the car will crank, start and stall almost immediately. if you have this, turn to ACC (dont start), choose DATA INIT, YES, turn car off and then perform self learn idle procedure

His car is not starting so he cannot do the self learning idle procedure.

joc - basically what you have done is resetted the power fc, if it has been tuned before which

sounds like it has then all the settings are gone if you havn't written them down.

Have you changed injectors or air flow meter?

before you start the car, under monitor check out water temp

then jump to the corresponding water temp correctio braket and try increasing the MS value for it. make sure you note down the numbers before fiddling. it may help it crank over a bit better when cold. cubes has done this and it sorted out his cold start problems for water temp at 10deg

Yeah im going to tune it but am waiting to get cam gears and replace timing belt as it due to be replaced also i want to boost it so i dont want to tune it till then.but i thought with the power fc you could just plug and play,just as long as you dont go flooring it every where,anyway so you think its the water temp,maybe i should do the learn procedure in the morning when its cold what do u think?

    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 馃槩 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.    
    • heh, aint no R32 ever meeting modern targa cage rules unless the driver is veeeery short OP, good luck with the sale, since its already in the land of freedom I'm sure you will find a good buyer.
    • meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)
